In this paper, a novel structure of 3D camera based on laser double triangulation displacement sensor is proposed. By placing two mirrors in the optical routes, double triangulation can be gotten by using only one CCD. Through designing the place and angle of these mirrors, the Scheimpflug condition could be met in whole measurement range of the sensor. And(More)
Ultraviolet (UV) radiation has a great impact on human health. Nowadays, the public basically gets information about UV radiance through weather forecasts. However, weather forecasts just provide rough and average predication for a certain large region. Since CMOS sensors in mobile phone cameras are very sensitive to UV, mobile phones have potential to be(More)
